Helu CAS 7783-7-5 Hale Hana Hana Hana Hana Hana. He aha nā mea hoʻolako o Hydrogen Selenide
ʻO ka hydrogen selenide, ʻike ʻia hoʻi ʻo ka waika hydroselenic ma kona ʻano wai, aia ke ʻano kemika H₂Se. ʻO 7783-7-5 kona helu CAS. He kinoea kala ʻole kēia pūhui i mea ʻawaʻawa loa a hiki ke puhi ʻia. Eia kekahi mau hiʻohiʻona o ka hydrogen selenide:
Nā waiwai kino:
ʻAno: ʻO ke kinoea kala ʻole me ka ʻala ʻala e like me nā hua popopo, ʻoiai ʻoi aku ka ikaika.
Puni paila: -41.4 °C.
Lae hehee: -85.4 °C.
Density: Ma STP, ʻoi aku ka dens ma mua o ka ea.
Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka wai a me nā mea hoʻoheheʻe polar.
Nā waiwai kemika:
Reactivity: He mea hoʻoikaika nui a hiki ke ʻā wale i ka ea.
Kaʻakika: I loko o ka wai, hana ia i ka waiʻakika nāwaliwali, hydroselenic acid (H₂Se).
Decomposition: Hiki iā ia ke decompose i elemental selenium a me ka hydrogen ma lalo o kekahi mau kūlana.
Hoʻohana:
ʻOihana Semiconductor: Hoʻohana ʻia i ka hana ʻana i nā pūhui selenium no nā semiconductors a me nā mea photovoltaic.
Analytical Chemistry: Hoʻohana ʻia ma ke ʻano he reagent i ke kemika analytical.
Noiʻi: Hoʻohana ʻia i ka noiʻi ʻepekema no ka hoʻohui ʻana i nā pūhui selenium.
Nā manaʻo palekana:
ʻona: ʻona loa ma ka inhalation, ʻoiai ma nā haʻahaʻa haʻahaʻa; hiki ke alakaʻi i nā hopena olakino koʻikoʻi me ka make.
Hiki ke ahi: Hiki ke hana i nā hui pahū me ka ea.
Ka lawelawe ʻana: Pono i nā kuʻina palekana koʻikoʻi, me ka hoʻohana ʻana i loko o nā puʻupuʻu fume a me nā lako pale pilikino kūpono.
Ma muli o kona ʻona a me ka mālama ʻana i nā koi, ʻaʻole i loaʻa maʻamau ka hydrogen selenide mai nā mea hoʻolako kemika maʻamau. Akā, hana pinepine ʻia ia ma ka pūnaewele ma nā hale hana a i ʻole nā mea hana i hoʻohana koke ʻia. ʻO nā mea hoʻolako kūikawā e mālama ana i nā ʻoihana e koi ana i ka hydrogen selenide ke kumu no ke kūʻai ʻana i kēia mea, ʻoiai ʻoi aku ka maʻamau o ka hana ʻana e like me ka mea e pono ai ma mua o ka mālama ʻana a lawe ʻia paha.
Hiki i nā ʻoihana e hāʻawi ana i ka hydrogen selenide a i ʻole nā mea hana mua e hoʻokomo i nā mea hana kemika kūikawā a i ʻole nā mea e mālama pono i ka ʻoihana semiconductor. E hoʻopaʻa mau i ka hoʻokō ʻana i nā lula kūloko a me nā alakaʻi palekana i ka wā e pili ana i ka hydrogen selenide, a mālama iā ia wale nō ma lalo o nā kūlana i hoʻomalu ʻia me nā ana palekana kūpono.
Ua haku ʻia ʻo Shanghai Wechem Chemical Co., Ltd. i kahi hui o nā poʻe akamai a me nā loea i loaʻa ka ʻike nui a me nā mākau ʻoihana i nā ʻano o nā kinoea kūikawā a me nā isotopes paʻa. Ma o ka hoʻomau mau ʻana a me ka noiʻi a me ka hoʻomohala ʻana, hoʻomaka mākou i nā huahana kiʻekiʻe a me ka maʻemaʻe kiʻekiʻe e hoʻokō i nā pono e ulu nei o kā mākou mea kūʻai. Inā makemake ʻoe i kēia huahana, e ʻoluʻolu e kelepona iā mākou i kēlā me kēia manawa!
